A floating leaf oscillates up and down two complete cycles in one second as a water wave passes by.The wave's wavelength is 10 meters.What is the wave's speed?
A)2 m/s
B)10 m/s
C)20 m/s
D)40 m/s
E)more than 40 m/s

Question

Quizplus · Accepted Answer

The wave's speed can be determined using the formula: 
speed = wavelength / period

Given: 
wavelength = 10m 
period = 1s / 2 = 0.5s (since the leaf oscillates up and down twice in one second)

Plugging in the values: 
speed = 10m / 0.5s = 20 m/s

Therefore, the wave's speed is 20 m/s.
